WIRE-LOOM.

Specification of Letters Patent.

Patented nec. 18,1917;

Application led November 25, 1916. Serial No. 133,285.

To all whom t may concern:

Be it known that I, FRANK W. CABBLE,

regulating the feeding of the wire from the v bobbin so as to prevent the wire from snarling, kinking or breaking as the shuttle passes back and forth.

To the accomplishment of the above objects, and to such others as may hereinafter appear, the invention comprises means for controlling the rotation of the bobbin as it enters and leaves the shuttle boxes. Suitable means being provided for stopping the rotation of the bobbin as it nears the end of its flight in either direction by entering either of the shuttle boxes.

Referring to the drawings:

Figure 1 is a perspective view of one of the shuttle boxes and adjacent parts with parts broken away, of a wire looml made in accordance with the present invention.

Fig. 2 is a transverse sectional view of a portion of the shuttle box and shuttle shown in Fig. 1.

In the drawings, 1 designates the batten which supports a reed 2 through which the ranks 3 and 4 of the warp-threads pass. In front of the reed and below it is the shuttlerace 5. Suitably supported adjacent the end of the race is one of the shuttle boxes 6 in which one of the picker-staffs 7 is arranged to shoot the shuttle 8 across the race. The parts just described are of usual construction and will be well understood.

In the present instance the shuttle box 6 comprises a stepped bottom plate 9 to one side of which is secured a front plate 10 havingatop plate 11. The shuttle 8 is held in position in the shuttle box by means of a forked spring member 11', one end of which is secured to a pin 12 provided with a spring 13 which acts to force the forked member 11 inward against the side of the shuttle. lVhen the shuttle has been shot out of the shuttle box the forked member 11 is adapted to engage the step 14 of the bottom plate so the forked finember 11 willy be in position to again engage the shuttle when it enters the shuttle box, the wire guide l5 on the shuttle passing between the forked ends of the forked member 1.1 as clearly Shownin Fig. 1. w

In the' present instance the bobbin 16 is made in the shape of a spool having suitable` flanged ends, the `same being `secured to a rod 17 rotatably mounted yin suitable bearings 18 and 19, the bearing 19 being provided `With a slottedspring pressed sl1de20 which facilitates the bobbinfbeing removed when desired. The bobbin 16V is wound with suitable wire 21 to bewoven which i passes out through a slot 22 in the sideof the shuttle and alsoout through the slot' 23 in the guide 1'5 as clearly shown in Fig. 2. In the present instance, and according to the present invention, the side ofthe shuttle adjacent the front plate 10 of the shuttle box is provided with a recess 24 in one end ofy which` is pivoted one end of a small brake lever 25, the free end of which is.v adapted to engage one of the flanged ends' of the bobbin 16. The free end of the brake lever 25 is normally held in retracted position out of engagement with the end of the bobbin by means of a small spring 26 secured to the inner side yof the shuttle adjacent the pivoted end of` the brake leve1.=

the shuttle .box is provided ywith a small recess 27 situated opposite-the free end`v` of ,i

the brake lever 25 when the shuttle is in rest position. vSuitab'ly pivotedtothe iside of'. thefront plate 10 is one end of an operating lever 28, the free end of which is provided with a cam projection 29 arranged to project through the small recess 27 and engage the free end of the brake lever 26 when the shuttle is in rest position, by the action of a. spring 30, which acts to force the free end of the brake lever 25 into engagement with one of the flanged ends of the bobbin 16 against the action of the spring 26 as clearly shown in Fig. 2.

Only one shuttle box has been shown in the drawing but the other shuttle box on the other side of the loom is constructed in the same manner and operates in the same way.

From the above description it will be seen that as the shuttle enters the shuttle box, the side of the shuttle adjacent the front plate 10 will force the cam projection 29 on the end of the operating lever 28 upward until just before the shuttle comes to' rest in the shuttle box, by which time the cam projec tion 29 has come opposite the recess 24 which it enters by the action of the spring 30 to engage the brake lever 25, forcing itinto, contact with one of the ianged ends of the bobbin to stop its rotation and prevent further feeding of the wire by the time the end of the shuttle comes in contact with the bumper 81 on the end of the picker-staff 7. l/Vhen in the operation of the loom the picker-'staff shown in the drawings is operated tol force the shuttle out of the shuttle box, it will be seen that the side of the shuttle adjacent the recess 24 will force the cam projection 29 of the operating lever 28 out of engagement with the brake lever 25, the small spring 26 being then free to act to raise the brake lever releasing the bobbin which is then free to feed the wire as it passes to the other shuttle box where a similar operating lever 28 acts to again arrest the turning of the bobbin. j

' From the' above description it will be seen that the wire on the bobbin is permitted to be fed only when the shuttle is in motion, for as soon as the shuttle comes to rest the bobbin is locked and remains locked until the shuttle is again in motion.

The means above described for arresting the feeding of the` bobbin as soon as the shuttle kcomes to rest prevents more wire being unwound from the bobbin than is necessary. i/Vhen on the other hand no means are provided for arresting the rotation of 'the bobbin when the shuttle has come to rest the bobbin continues to rotate a few turns, thereby permitting the wire to become loose and 'slack allowing it to kink and snarl and often resulting in the breaking of the wire, these disadvantages, however', are all overcome by the means above described for stopping the bobbin as soon as the shuttle comes to rest.

VWhile the invention has been described with particular reference to the details of construction, the same is not to be considered as limited thereto, as many changes can be made and still fall within the scope of the invention set forth in the following claims.

What I claim is l. A wire loom comprising in combination a shuttle box and a shuttle having a rotating bobbin, said bobbin being provided with flanged ends, a pivoted brake member mounted in a recess in said shuttle box and adapted to engage one end of said bobbin, means for maintaining said brake member in an inoperative position, said shuttle box being provided with an opening, a lever mounted on the shuttle box and projecting into said opening, means mounted upon the end of said lever for engaging said brake member, and means for maintaining said first mentioned means in engagement with said brake member.

2. A wire loom comprising in combination a shuttle box and a shuttle having a rotating bobbin, a pivoted brake member mounted in a recess in said shuttle box, said brake member being adapted to engage the rotating bobbin, means for maintaining said brake member in an inoperative position, a lever mounted on the shuttle box, means upon the end of said lever for engaging said brake member and means for maintaining the last mentioned means in engagement with said brake member.

ln testimony whereof I have signed this specification in the presence of two subscribing witnesses.
